DOOR-CHECK.

Specification of Letters Patent.

Patented Apr. 25, 1911.

Application filed September 20, 1910. Serial No. 582,948.

To all whom it may concern:

Be it known that I, Gnonon E. HASSMANN, a citizen of the United States, residing at Litchfield, in the county of Montgomery and State of Illinois, have invented certain new and useful Improvements in Door- Checks, of which the following is a specification. l i This invention relates to improvements in devices for securing doors at any desired point either closed, fully opened, or partly opened, and has for its object to simpli and improve the constructionand increase the efiiciency and utility of devices of this character.

Another object of the invention is to provide a device of this character which may be actuated by the movement of the lock or latch spindle.

With these and other objects in view the invention consists in certain novel features of construction and arrangement of the parts as hereinafter shown and described and then specifically pointed out in the is illustrated the preferred embodiment o the invention.

Figure 1 is a view of a portion of a door and its frame and casing includingone of .the hinges with the improved device applied.

Fig. 2 is an enlarged front elevation of the Fig. 3 is a section on the line 3-3 of Fig. 2. Fig. 4. is a sectional detail of the knob attachment portion of the im roved device.

tional door, a portion 0 rresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

The improved device may be applied to doors or other swinging structure of any size. For the purpose of .illustration the improved device is shown ap lied to a convenwhich is represented at 10 with the frame at the hinge side at 11 and the frame at the latch side at 12.

The improved device resembles an ordinary hinge having leaves 13 -14 and a pintle 15. The leaf 13 differs from an ordinary hinge pintle by being provided with an inwardly directed stop-web 16 and stop-lugs 1718 at the ends of the stop-web, and the leaf 14 differs from an ordinary hinge-leaf by being provided with a guide keeper 19. The leaf 13 is connected to the hinge casin or frame 11, While the leaf 14 is connected to the door by screws in the usual manner with the pintle located in vertical alinement with the p'intles of the ordinary hinges of the door.

Mounted for rotatlon upon the pintle 15 is a stop-collar 20 having a plurality of recomes 21 spaced apart in its periphery. The collar 20 is so arranged upon the pintle that one ofits recesses engages constantly with the stop-rib 16, while the ends of the collar extend between the stop-lugs 17-48. By

fy 1 this means the stop-collar is coupled to the leaf 13 both for rotative and longitudinal movement relative thereto. Slidable through the guide-kee er 19- is a bolt 22 having a slot 23 and held 5 idable within the keeper by a pin 24. The keeper 19 is formed with a recess to receive a spring 25, which is connected at one end to the pin 24 and at its other end to the bolt 22, the-spring operating to maintain the inner end of the bolt in yieldable engagement with one of the recesses 21 of the collar 20. By this arrangement the lug 14 may be locked to the collar 20 and through the collar to the other leaf 13 at any desired point within the range of the recesses. One of the recesses of the collar is so located that the bolt 22 will engage therein when the leaves 13-14 are in alinenient transversel or when the door is in closed position, an then when the door is to be opened the bolt is withdrawn, and when the door'has been opened to the desired extent, the bolt is released and engages in the nearest recess 21 and thus holds the door firmly in the adjusted position, and is releasable only by a ain withdrawing the bolt. By this means 1t will be obvious that the door may be held at any desired point within the range of the recess 21 in the collar 20, and by providing a plurality of the recesses spaced a short distance apart, the range of the device is materially increased.

Any required means may be employed for actuating the bolt 22, but will preferably be so coupled to the knob or latch spindle that when the knob is rotated to open the door the bolt will be actuated, and an approved mechanism for accomplishing this result is shown in the drawings. The knob spindle is represented at 26 and the knob at 27. v

screw utilized to couple a small lever 29 to the knob, the leverbeing thus arranged to rotate with the knob. At its outer end the lever 29 is connected b a pull-wire or cable 30 to the bolt 22 an arranged to be guided over a suitable guide-pulley 31 upon the door 10. By this simple means it will be obvious that when the door is to be opened the first movement of the knob s indle will cause the withdrawal of the olt 22 and release the door which may then be opened to any r uired extent and automatically locked w en the knob is released.

, The improved device is simple in construction can be inexpensively manufactured and applied without makin any change in the door or in the casing. he lmproved device may be manufactured of any required material and of any required size to adapt it to doors of difi'ferent weights and sizes.

Having thus described the'invention what is claimed as new is A door check comprising two leaves adapted to be connected res ectively to a door and its frame, one of sai leaves having a stoprib, a pintle uniting said leaves, a stop-collar having a plurality of recesses spaced a art and carried by said (pintle, one of sai vrecesses being arrange in constant engagement with said sto -rib, and a sprin controlled, bolt carrie by the other 0% 5 leaves and adapted to engage any one of said recesses to lock said leaves against relative movement.
